CONCLUSIONS: Our procedure leads to successful (re)use of data in FL-based consortia without the need to impose a common schema at every point of origin of data.

Exposure to feelings of another can shape how we feel and think in that context. We propose that exposure to the feelings of multiple others carries broader implications that extend beyond the exposure context. We argue that people identify patterns of affective reactions in the social group, which leads them to infer affect norms. These norms, in turn, serve as benchmarks for subsequent social judgments. In four studies (N = 418), three of which were preregistered, we exposed participants to...

Inflammatory injury to the intestine triggers a reprogramming of the intestinal epithelium to a fetal-like state that drives rapid restoration of the epithelial barrier. Although the intestinal microbiota is a key modulator of inflammation, its role in influencing epithelial fetal-like stem cell reprogramming and consequent restitution remains unclear. Using irradiation (IR) injury as a model for small intestinal epithelium injury and repair, we found that the intestinal microbiota accelerated...

Mutations in the X-linked MECP2 gene cause the progressive neurodevelopmental disorder Rett syndrome. Pathogenic missense mutation hotspots exist in the protein's Methyl DNA binding Domain (MBD), and the Nuclear receptor Co-Repressor (NCoR) Interaction Domain (NID), indicating these regions as critical for MeCP2 function. The NID binds to a co-repressor complex allowing transcriptional repression at target genes. A putative RNA Binding Domain (RBD) was identified that overlaps with the NID, yet...

Deciphering how genes interact within human cells is essential for understanding their functional wiring and for developing targeted therapeutic strategies. In this study, we present a genome-scale map of genetic interactions in the human haploid cell line HAP1, based on CRISPR-based perturbation of ∼4 million gene pairs. The resulting network comprises ∼89,000 high-confidence gene-gene interactions, organizing genes into hierarchical modules corresponding to protein complexes and pathways,...

CONCLUSIONS: Our findings show that aggregate wearable data often fail to generalize across populations, oversimplifying pregnancy-related physiological and subjective changes. This simplification can obscure individual trajectories, leading to generalized insights that may not reflect many pregnant women's experiences. Our results highlight the impact of heterogeneity on pregnancy outcomes, emphasizing the need to move beyond one-size-fits-all models and leverage DHT for personalized care.

CONCLUSION: These findings confirm the high prevalence of constipation-predominant intestinal dysfunction in patients with MWS. Collectively, our findings support further investigation of associations among feeding difficulties, a lower proportion of meat in dietary composition, and an altered fasting plasma neurotransmitter profile (including lower serotonin in a small subset), which may be relevant to gut dysmotility in patients with MWS. This diet-neurotransmitter axis offers a working model...

Objectives: To determine the incidence and outcomes of SARS-CoV-2 infection and to evaluate seroconversion rates and quantify antibody responses to COVID-19 vaccines in two cohorts of persons living with HIV at a possible higher risk of poor outcomes (HCV coinfection and those over the age of 65 years). Methods: We included participants from two established cohorts of persons living with HIV, those who were older than 65 years of age, and those with hepatitis C (HCV) co-infection. Four hundred...

Objectives: Allogeneic stem cell transplantation (HSCT) is curative in acute myeloid leukemia (AML) but is limited by relapse and non-relapse mortality (NRM). Metabolomic prognostic value is unclear. We assessed whether plasma metabolite profiles at diagnosis, pre-transplant, and post-transplant are associated with overall survival (OS) and cause-specific mortality. Methods: We retrospectively analyzed plasma metabolites from 63 AML patients undergoing HSCT (263 samples). Results: Higher levels...

In 2016, the Japan Children's Cancer Group launched a nationwide research initiative to provide central diagnosis incorporating pathology review and molecular profiling for pediatric central nervous system (CNS) tumors. Over the first eight years, 2224 cases were registered. Non-next-generation sequencing analyzes, such as pyrosequencing and NanoString, were routinely performed, mainly for glioma, medulloblastoma, and ependymoma. Additional analyzes, including methylation profiling and RNA...

BackgroundResearch indicates a significant overlap between transgender and gender-diverse (TGD) and autistic identities. This intersectional population has higher risks of mental health challenges and worse mental health outcomes than individuals with just one of the two identities. Limited research focuses on adults at this intersection and their care access needs. To better characterize this population in the Canadian context, this study examines the population referred to Canada's largest...

CONCLUSION: Neutralizing antibody levels to Omicron JN.1 subvariant were identified in 79% overall but in only 56% with vaccine only immunity. The presence or level was not associated with protection form a new SARS-CoV-2 infection over 10-months. This data supports the development of pan-coronavirus vaccine to expand protection against emerging variants.

Self-fertilization reduces genetic diversity compared to outcrossing and hypothetically decreases the ability to adapt to diverse environments. Among Caenorhabditis nematodes, self-fertilization evolved three times independently in Caenorhabditis elegans, Caenorhabditis briggsae, and the more recently discovered Caenorhabditis tropicalis. To survey C. tropicalis genetic relatedness, the influence of geography and niche on species-wide variation, and the signatures of selection, we collected 785...

NMR spectroscopy is a powerful tool for studies of protein dynamics over timescales extending more than twelve orders of magnitude, with motion queried at many of the backbone and sidechain positions in the molecule of interest. NMR experiments can, in principle, provide atomic resolution descriptions of excited conformational states that are sparsely populated and transiently formed-i.e., invisible, and there are examples of such structures in the literature. However, in other cases, the NMR...

In the face of rapidly accumulating genomic data, our ability to predict key mature RNA properties that underlie transcript function and regulation remains limited. Pretrained genomic foundation models offer an avenue to adapt learned RNA representations to biological prediction tasks; however, existing models are trained using strategies borrowed from textual domains that do not leverage biological domain knowledge. Here we introduce Orthrus, a Mamba-based mature RNA foundation model pretrained...

Children with medical complexity (CMC) have chronic conditions with multisystem comorbidities requiring high-intensity, coordinated care. A substantial yet often invisible aspect of this care is the administrative workload borne by parents and caregivers. This 'unseen and undervalued work' encompasses the relentless administrative labour required to secure services, complete forms, manage appointments, advocate across fragmented systems, and coordinate supports frequently without adequate...

The rapid advancement of unmanned aerial vehicles (UAVs) in disaster response and environmental monitoring has underscored the growing importance of real-time object detection within UAV swarm networks. However, the non-independent and identically distributed (non-IID) characteristics of data in UAV networks present significant challenges to model convergence and adaptability. To tackle these challenges, this study introduces a robust federated UAV object detection framework tailored for non-IID...
